Re: Room Size and 7.1


When I set the speaker distances from a center rear spot in the back of the room I am 13 ft away from the fronts I am 13 feet away from the center I am 13.5 feet away from the front sub Now it gets tricky . (my recliner is only 3 feet away from the right surround and 5 feet away from the right rear surround but I am 12 feet away from the left surround and 10 feet away from the left rear surround ) Now My Wifes recliner is the same way with right and left surround and rear surround .) So I just set both of them as though we were sitting in the center of the room..) Sounds Ok but I cant here the surrounds very good... My speaker levels are all set to 10 ( Highest setting ) ????

Are you using a sound level meter to set the levels?

Re: Room Size and 7.1


I could .. I did it mostly by ear but I can borrow one .. I have a good buddy of mine that should have one from back in the day when he was building his home theater room.. I will call and see if he has one.. I did find out that someone had gone into my speaker set up and had changed my front speakers to small,and my surrounds to large .. So I switched that back and it made a big difference.. My wife loves to push all them pretty buttons...

Re: Room Size and 7.1


Found the problem the front fishers were playing really loud when I did the volume sweep this is due to the crossovers in these speakers being totally screwed up .. I have new crossovers coming for these so that problem will be solved.. So for now I had to drop the level on the front L,R - 3db.. Or on 7 instead of 10 according to the pioneer vsx-516.. On another note I couldn't get my wife to be quiet long enough to use the extech type 2 meter that I just borrowed.. So I am going to wait until Football comes on and give it a shot .. My wife gets real quiet when football is on

Re: Room Size and 7.1


You should start all the levels at 0, do a run with a meter (the only way to do it accurately), and then adjust everything around the speaker whose output falls in the middle of the output range. Turn up our main volume until that speaker measures 85dB (if that's too loud to get away with, do 75dB instead, or send the family outside for a while) and remeasure and adjust. In other words, if you're measurements look like this, make these adjustments:

L = 82 = +3
C = 85 = 0
R = 82 = +3
Rs = 87 = -2
Rb = 84 = +1
Lb = 84 = +1
Ls = 87 = -2

In the end, you should have one or more speakers at 0, and a few minus a few dBs, and a few plus a few dBs.

Re: Room Size and 7.1


Worked on it and everything is pretty close my center is a little higher and Left and Right are alittle lower .. Others about the same as you predicted.. Nice sound .. My wife is even impressed.. I got in trouble for picking an old 4:3 60 RPTV for free off of craiglist today though.. Coolant fluid had leaked all over the boards but I did manage to salvage a nice 60" 4:3 frenel lens ( SCREEN ) It was a Mistabitsy VS-60603

Re: Room Size and 7.1


I built some real nice metal stands for my front fisher st-828's yesterday they are made form old metal chairs it lifts them up about 16 inches and gets them where the mids and tweets are just at listening level instead of them sitting on the floor.. also I am debating on moving all of my A/V equipment over to a shelf next to my recliner this way it will take all of the A/V equipment off of the top of the speakers and away from the veiwing area . I guess the bad thing about doing this is having to run a 30 foot HDMI cable as well as a couple of 30 foot long compnent video cables I will have to work on this idea. Also since my Reciever has no HDMI just 1 HDMI on the TV itself I was thinking about running one long HDMI cable and then buying a HDMI splitter unit where it will give me about 3 more HDMI ports .. This is going to be a all day job ..
